Specification of Letters Patent.

Patented Aug. 15, 1905,

pplieation filed October 12, 1904. Serial No. 228,136.

lie it known that we, Fnnnnm'oi( i/V. SMITH. and WILHELM J. SrrLnrNo, citizens of the United States, residing at Brooklyn, in the county of Kings and State of New York, have 'invented certain new and useful Improvements in Sash-Operating Devices, of which the following is a specification.

rihis invention relates to windows, and par-` ticularl y to means 'for simultaneously operating a number' or L cluster of sash therein at one operation to open and close the same. .lhere is a class of buildings, of which what are known as powenhouses are examples, in which a maximum of both light and ventiiation is peculiarly desirable. Abundance of light is necessary for the proper care and oversight of machinery, which in a well-ventilated lbuilding' is less likely to become overheatcd. The comfort of workmen also demands maximum ventilation. in this class of buildings, while the window-openings are as large as deference tothe stability of the structure and its walls will permit, small sash or panes are generally employed, principally 'for the sake of economy. lt has been the more general practice to pivotally mount each sash .in its supporting-frame, whereby the sash lwill swing from an open to a closed position, and vice versa, and to save time and labor in both opening and the closing` operations, parn ticularly the latter upon the occurrence of a rainstorm, likely to result in wetting' and damaging' the machinery unless the sash are quickly closed, it is desirable to provide handoperated mechanisms adapted to open and close a group or cluster of these sashat a single operation. The requirements of such mechanism obviously are that it shall be simple and easy of operation, that it shall be comparatively inexpensive in cost of construction and application, require but little time and effort in manipulation and be positive in operation, be itself practically non-interferent with either light or ventilation, not likely to get out of order, and be the subject of easy repair in case of accident.

Vire do not claim, broadly, the idea of providing mechanism for siniiultaneously operating a plurality of swinging sash, our invention residing in the simplification of such devices, in means for securing ease of operation and quick action, in the reduction of the number of parts heretofore found to be essential,

and in various details of construction and in combinations of parts, all as hereinafter described, and particularly pointed out in the claims.

Our invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification, in which- Figure l is an interior elevation of a window constructed and equipped with operating mechanism embodying our invention. Fig. 2 is an enlarged transverse vertical section of the lower portion thereof. Fig. 3 is a sectional plan view thereof. Fig. t is a sectional elevation, on a still larger scale, with portions broken away. Fig. is a view of the operating-lever and connections.

Referring now to the drawings in detail, we have shown in Fig. l the lower portion of a window-frame, preferably of the common and wellknown sheet-metallic construction, adapted to be permanently secured in any suitable manner within an openingI in the wall of a building and comprising the usual stiles and ails to subdivide the same into a plurality of smaller openings of uniform size, each adapted to accommodate an individual movable close-fitting sash. rl,`he specific manner of sub division by the stiles and rails, and therefore the relative arrangement of the sash, is not material to the present invention, although a frame providing for vertical rows of sash is contemplated. W e prefer to employ a frame F. subdividing the opeiiii'ig` into a plurality of sash-opening clusters, each cluster accommo dating three sash S, i5', and Si in vertical alinement. Eachof these sash is pivoted at or near each upper corner thereof to the frame and swings outwardly therefrom, (see Fig. 9.,) a suitable seat being provided into which the sash closely [its when closed. Projecting in wardly from each of said sash is a meinber having the function of one arm of a bell-crank lever of which the sash forms the other arm, whereby upon application of power in a vern tical direction movement of the lower edge of said sash in a substantially horizontal direcm tion will result. YV'hile we have shown this member in the form of a tripod with two legs (i and 'Z' secured to the upper member of said sash and the third leg 8 secured to the middle of the lower member thereof, which construction we have found to give greatest strength. and rigidity, it will be apparent that a single arm or lever may be employed, as it may be considered that the power is transmitted to the sash through the leg 8, braced, if desired, by the legs 6 and 7, or through the arm, braced by the leg 3. At the end of this sash-operating member or, in the specific construction shown, at the union of the three legs 6, 7, and 8 is pivotally secured a collar 9 to provide for vertical adjustment of the rod or bar 10, which is secured therein by means of the set-screw 11 or other form of clamping device. This rod or bar is similarly secured to the operating members of the other sash in this cluster and serves to link them together and provide for synchronous movement of the sash.k

Preferably secured to the window-sill and each projecting inwardly from substantially the middle portion thereof under each clusteropening are the arms 15, 15, and 15, carrying' the shaft 22, rotatable in bearings in the extremity of said arms. lo this shaft is keyed or otherwise suitably secu red the crank-lever 17. Suitably secured to and projecting inwardly from the building-wall is the support 12, to the end of which is pivoted a vertically-swinging controlling-lever 13, which is preferably provided with an operating-handle 111. lhe connecting-rod 18 is pivoted at each end, respectively, with the extremity of the lever 17 and to the controlling-lever 13 atan adjustable distance from the pivoted end thereof. Similarly keyed or otherwise suitably secured to said shaft 22 is the lever 21, a connecting-rod 2O being similarly pivotally secured at each end, respectively, to the extremity of the lever 21 and lower end of the rod or bar lO. 1t will be apparent that the complete upward stroke of the controlling-lever 13 will operate to rotate the shaft 22, and thereby depress the bar or rod 10 and cause the sash connected thereto to swing outwardly, preferably to an inclination of about forty-five degrees from the vertical, as shown in Fig. 2 by dotted lines. It will be furthermore apparent that by increasing the length of the shaft 22 any reasonable number of clusters of sash in a single horizontal row may be simultaneously operated by a single controlling-lever.

To operate the sash in the next succeeding horizontal row of clusters above, which are identical in construction and operation, we provide a similarly-supported shaft 22, to which crankarms 17 17 are secured. Mounted upon the building-wall, preferably immediately adjacent to the support 12, is the support 12, providing a fulcrum for the operating-lever 13', which is similarly connected to a walking-beam 23. The shaft 22 thus provides a fulcrum for the walking-beam 23, which is loose thereupon and operation of which, therefore, is non-interferent with independent rotation of said sha-ft and the mechanism for operation of the lower row of clusters. Desired rotation of the shaft 22 is effected by means of the rod 25 connecting the other arm of the walking-beam 23 with the crank-arm 24:, xed upon said shaft 22. The sash in the upper row of clusters are therefore operated in a precisely similar manner, the rod 25 having been interposed to permit the location of the operating-lever at an easilyaccessible point.

It will be apparent that any number of hori- Zontal rows of clusters of sash may be similarly provided for and the controlling-levers located near the floorand comparatively near each other, whereby the sash of the entire window may be opened or closed with the least possible effort and loss of time. It will also be apparent that in securing the sash-operating arms or members to the middle instead of at one of the side edges of the sash we insure greater strength and rigidity and prevent warping strains.

Many modifications of details of construction of a device designed to carry our invention into enfect will doubtless readily suggest themselves to those skilled in the art to which it appertains, and we therefore do not desire to limit our invention to the specific construction herein shown and described.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination,\vith a plurality of Inovable sash in vertical alinement and each pi'ovided wit-h a controlling member projecting' from substantially the middle of one of the sash-rails and braced from the other rail, of a rod having connection with each of said members, and means for raising and lowering said rod.

2. The combination, with a plurality of outwardly-swinging sash in vertical alinement and each provided with a controlling' member projecting inwardly from substantially the middle of one of the sash-rails and braced from the other thereof, of a rod having pivotal and adjustable connection with each of said members, and means for raising and loweringsaid rod.

3. The combination` with a plurality of movable sash in vertical alinement and each provided with a tripod-controlling member having one leg secured to substantially the middle of one sash-rail and two legs to the other rail, of a rod having connection with each of said members, and means for raising and lowering said rod.

4. The combination, with a plurality of vertical rows of movable sash each provided with a controlling member, and a rod for each row having connection with each of said members therein, of a shaft, means for rotating said shaft, a plurality of crank-arms secured to said shaft. and a connecting-rod between each rod and its operating-crank.
